Abstract (en)
[origin: EP1334962A1] There is provided a method for producing easily highly-purified acylphenylalanine that is useful as a raw material of pharmaceutical products and the like, which comprises the step of reacting an acid chloride with phenylalanine in a mixed solvent of an organic solvent and water, while keeping the solvent under the alkali condition by using potassium hydroxide.
